TRANSFER MECHANISM FOR REPLENISHING LOOMS.

Application filed June 25, 1917.

To all whom it may concern:

Be it known that I, CLAUDE T. WOMACK, a citizen of the United States, and a resident of Phoenix City, in the county of Lee and State of Alabama, have invented certain new and useful Improvements in Transfer Mechanism for Replenishin Looms; and I do hereby declare the fol owing to be a full, clear, and exact description of the invention, such as will enab others skilled in the art to which it appe ains to make and use the same.

This invention relates to improvements in filling replenishing looms and more particularlv to the transfer devices therefor.

With prior constructions of transfer mechanism for filling replenishing looms, danger of breakage of the bobbins has occurred by reason of the tendency of the transfer finger employed, to become distorted (as frequently happens) and result in splitting the bobbin in forcing the same from the magazine to the shuttle, and in some instances, breakage of the shuttle has been caused by engagement of the transfer finger therewith on account of the bending of said finger.

An object of my present invention is to so construct transfer devices for filling replenishing looms, as to eliminate breakage of the bobbins and shuttle and to obviate the danger to the operator, as heretofore encountered when a shuttle is broken with possibility of accident from broken pieces.

A further object is to construct the transfor devices in such manner that the cost of loss from breakage of bobbins and shuttles shall be saved without materially increasing the cost of construction of said devices.

A further object is to so construct the transfer devices that the same shall be readily adjustable for bobbins of different lengths.

With these and other objects in view, the invention consists in certain novel features of construction and combinations of parts as hereinafter set forth and pointed out in the claims.

In the accompanying drawings; Figure 1 is a side elevation partly broken away illustrating the application of my invention; Fig. 2 is a plan view, partly in section, and Fig. 3 is an end elevation partly in section.

1 represents a rotary magazine or carrier for filled bobbins 2 -the latter being held Specification of Letters Patent.

normally in position therein by means of springs 3. At the proper time, controlled by suitable mechanism well known in the art and not necessary to describe herein, a shuttle 4 will become properly positioned, as shown in Fig. 1, to have its depleted bobbin 5 ejected and to receive a filled bobbin 2 from the magazine. A filled bobbin 2 at this time will be directly over the shuttle.

An arm 6 is loosely mounted on a fixed shaft 7 and provided at its free end with a head 8 adapted to engage one end of the bobbin 2. The arm 6 is also provided at, its free end with a laterally projecting, internally threaded boss 9 to receive one end portion of a threaded rod or stud 10, which latter is thus adjustably connected with the boss 9 and is retained in position by means of a nut 11.

The shank 12 of a transfer finger 13 is perforated for the accommodation of the threaded rod or stud 10,said finger being elongated in form and dished as at 14 to engage the body of the filled bobbin at an appreciable distance from the end thereof which is engaged by the head 8 on the arm 6. The shank 12 is disposed at right angles to one end of the finger 13 and is held at any desired adjustment on the rod or stud 10 by means of nuts 15, 15. Thus it will be seen that the transfer finger may be readily adjusted for bobbins of diflerent lengths, that it does not engage the mechanical structure of the bobbin per se, and that it can never strike the shuttle during the transfer of a bobbin thereto from the magazine.

Normally, the transfer device is kept out of contact with the filled bobbin by means of a spring 16 coiled on the hub of arm 6 and attached at one end to a collar 17 fixed to the shaft 7, the other end of said spring engaging the arm 6.

When a shuttle is in position to receive a filled bobbin from the magazine, the arm 6 will be operated by suitable mechanism (not shown) to cause the head 8 and finger 13 to force a filled bobbin out of the magazine and into the shuttle, and at the same time the entrance of the filled bobbin into the shuttle will cause the depleted bobbin 5 to be ejected from the shuttle.

Slight changes might be made in the details of construction of my invention without departing from the spirit thereof or iting its scope and hence I do not wish to restrict mysel to the precise details herein set forth.

'Having fully described my invention what I claim as new and desire to secure by Let ters-Patent, is 2- 1. In transfer means for filling replenishing looms, the combination with a bobbin carrier, of= transfer devices comprisin a movable arm having a head at one eng, a rod removably and adj'ustably secured at one en tosaid arm, a finger carried by said mmova .le rod and adapted to engage the filled bobbin, between its ends and a spring connected with said am and operating normany ,to maintain said head and finger out of en agement with the filled bobbin.

[2,. in transfer means for. filling replenishing-looms, the combination with a bobbin carrier, of transfer deviees oomprising a mom, le an'ln having a head at its free end d'eng'ag'e an and-portion of affilled bobbin, a threaded riod projecting laterally from 6 1;; g! (in; .pnte ag my be manned msaid arm, and. a finger'adjustable on said rod and disposed to engage a filled bobbin in the carrier between and removed apple giable distaneesfrom'both ends at said bob 3. In transfer means for filling replenishing looms, the combination with a bobbin carrier, of transfer devices comprising a movable arm having a head and a boss at one end, a laterally projecting threaded rod entering said boss and detachably secured to the latter, an elongated H er to engage an intermediate pol'fin of all led bobbin, Sam finger having a] ank mounted on said threaded rod, ands-nuts on said rod to retain the, finger at. any desired adjustment.

Inltestimony whereof, I have signed this spe'ifi cation m the presence of'tvv'osnbs'cribmg witnesses.
